O AUMENTO DA RESISTÊNCIA MECÂNICA DOS NÓS DO BAMBU COM REFORÇO DE FIBRA DE VIDRO

Abstract

Steel has consolidated employability in the civil construction sector due to its physical and mechanical properties, however, its production causes great environmental damage due to the high energy consumption that results in increased carbon dioxide emissions from industries, river contamination with effluents that are emitted in its manufacture, and besides all that, it is not a renewable raw material. Seeking alternatives that have minimal environmental impact, without compromising the result known for steel, this work was developed presenting a methodological research of the bamboo Phyllostachys pubescens with the reinforcement of the knot involving it with fiberglass to increase its performance, which can be considered a new material alternative for structural use in civil engineering. As the environment is increasingly demanded by society and the consumer market, the civil construction sector would be no different. To establish a comparative parameter that proves the improvement in the strength of bamboo with the reinforced knot, compression, shear and traction tests will be carried out on Phyllostachys pubescens bamboo, the CP's were prepared with some natural treatment (immersion in water), chemical treatment (application copper, chromium and boron) and untreated. Finally, it is intended to prove the increase in mechanical strength with the application of fiberglass from the bamboo knot to arouse a curiosity in Brazilian professionals, generating an increase in its use in civil construction and consequently national standardization, as they exist in other countries like China and Colombia.
